Description

The present invention relates to the field of communications, and in particular to a load balancing processing method, apparatus, wireless access node, and user equipment. BACKGROUND OF THE INVENTION With the maturity of wireless technologies, especially the development of mobile communication technologies, more and more mobile users hold mobile devices for communication of voice and data content. In the existing mobile communication network architecture, the wireless access part is mainly composed of a base station node (NodeB) and a radio network controller (RNC) node in the 3G network, and only one node (eNodeB) exists in the extended wireless network. These nodes are responsible for the allocation and management of radio resources and to communicate information between the mobile terminal and the core network nodes. 1 is a schematic diagram of a network architecture of an evolved mobile communication system in the related art. As shown in FIG. 1 , taking an evolved network architecture as an example, an X2 interface exists between wireless access nodes (eNodeBs), and wireless access and core network parts exist. S1 interface, used for communication between nodes. For a core network node, the number of mobile devices it can accommodate reflects the capacity of the network load. Generally, a core network node is connected to multiple wireless nodes, and the wireless nodes are distributed in different locations, and are used for providing functions for accessing core network node services for users in different geographical locations, and can be configured for each wireless access node. The maximum number of users allowed to access, the sum of the maximum number of allowed access users for all wireless access nodes configured, and the maximum load capacity of the core network node is not allowed. In the event of an overload, it may cause network anomalies to fail to provide services, and even more so. In order to solve the problem that a large amount of load is required in a short period of time and the service is overloaded, there are various technical methods to achieve load balancing:

(1) Random access delay indication. When a wireless access node (hereinafter referred to as an access node) has access to a mobile device that is currently close to saturation, the maximum number of allowed accesses is reached. When a new mobile device in the idle state requests access, the access node indicates a BackOff Identity in the access control part through a random access response (Radom Access Response), and the mobile device receiving the delay indication is Re-initiating the random access procedure after a period of time;

(2) Wireless resource establishment rejection. When the new mobile device and the wireless access node process the resource establishment process, the access node transmits to the mobile device through the displayed RRC Connection Setup Reject, and the mobile device does not initiate the calling and receiving in the subsequent period of time. Call business (3) By updating the relocation context information. When the same wireless node is connected to two different core network nodes, when the mobile device requires access to the already saturated core network node, the wireless access node instructs the mobile device to initiate the tracking by releasing the existing resources and the established connection. Tracking Area Update, the wireless access node transmits the initial UE information to the core network node that is not included through the SI interface, relocates the UE information through the interaction of the core network node, and provides services to the user in the new core network node. ;

(4) Resource query and redistribution. The wireless access nodes continuously adjust the maximum number of loads allowed by each wireless access node by querying the number of access tasks per wireless access node;

(5) Borrowing of wireless resources. When the number of connected users of the wireless access node tends to be saturated, preempt the neighboring and unsaturated wireless access node resources to provide services for the mobile device; in the foregoing processing manner of the related art, the wireless access node Its own functions can avoid the overload to achieve the purpose of load balancing to a certain extent. But these technical approaches are at the expense of delaying the user experience for user service and affecting other wireless nodes to serve their coverage area users. Method (1) and method (2) delay user access, and when the loaded load consumes resources for a long time, it cannot provide services for new users. The method (3) achieves equalization by releasing the user who has already occupied the resource and relocating to other idle nodes, but the method may cause the user to be interrupted, and there is an explicit time delay for re-establishing the wireless resource. The method (4) is a communication interaction between the wireless access nodes, and dynamically adjusts the maximum number of access users of each node. This type of load balancing is not based on users in the actual coverage area. Once new user access occurs after adjustment, repeated adjustments occur, which increases the communication burden between network nodes and redundant signaling. The method (5) increases the priority of the saturated state node, and borrowing the resources of the neighboring node still causes the borrowed node to borrow a large amount of user access. Uncertainty and uncertainty, and there may be cases where neighboring node resources are also in a state of saturation and cannot be borrowed, resulting in failure to provide services to users. Therefore, in the related art, when processing overload balancing, there is a problem that delays serve the user, interrupt the service, and frequently adjust to increase redundancy and uncertainty, resulting in a reduction in the user experience.

In order to avoid the above problems in the related art, in order to avoid that the wireless access node has too many mobile devices, the overload cannot provide services for the user, and to reduce the impact on the existing user services and redundant signaling during load balancing, A load balancing adaptive method based on user equipment, thereby achieving the purpose of load balancing, improving network parameter configuration adaptability and user experience. The technical solution mainly includes the following processes: Cell Global Identity (CGI) is used to uniquely identify a radio access node and cell information in a node. For an Evolved Universal Terrestrial Radio Access Network (EUTRAN) and a Terrestrial Radio Access Network (UMTS) wireless communication system, the CGI content includes a network identifier (for example, Public Land Mobile Network (PLMN) identity and cell identity (Cell Identity). For GSM EDGE Radio Access Network (RAN) wireless communication system, CGI also adds location area code ( The load balancing adaptive method includes: when the mobile device establishes a wireless resource with the wireless access node, the CGI information is read from the broadcast channel of the cell, and when the mobile device releases the wireless resource and returns to the idle state, Recording the cell identity CGI for which the service was last served. When a large number of devices move to the coverage of the new wireless access node, when establishing a connection with the wireless access node when the service needs to be performed, the air interface standard signaling radio resource establishment request is made. (RRC Connection Setup Request) Message explicit addition letter Last CGI indication to the wireless access node currently accessed, if the set of predetermined time T, the required number of mobile units access _{N_} USer reached a predetermined value N_t_user_max, and the current wireless access node has access to appear Load capacity N_access and N_user After the addition exceeds the maximum allowed access value N_m _ax _all _0we d defined by the wireless node, the current wireless node adjusts the maximum allowed access number to N_max_allowed+N_user, and accepts the new user equipment to allocate radio resources for it, and according to the user. The Last CGI information carried by the device in the RRC connection setup request message extracts the number of user equipments having the same CGI information (N_same_cgi_l, N_same_cgi_2, ..., N_same_cgi_n), and N_same_cgi_l+N_same_cgi_2+...+N_same_cgi_n=N_user. The current eNodeB can send a message (Load Number Adjust, N_same_cgi_i) to different original wireless access nodes according to the CGI information through the X2 standard interface, where i=l, 2, ..., n. Each access node receives the original message are the maximum number of users allowed access to the adjustment, the original access node gi_i adjusted according to the maximum permitted access number N_ _Sa me_ _C users M_max_allowed-N_same_cgi_i. This ensures that the maximum number of allowed accesses maintained for the core network node is unchanged. The maximum number of allowed accesses maintained by each access node, as the terminal moves, dynamically adjusts when an overload occurs. FIG. 10 is a general flowchart of a mobile device load balancing method according to an embodiment of the present invention. As shown in FIG. 10, the process includes the following steps: Step S1002: A UE records a current wireless access node (eg, an eNodeB) uniquely identifies a CGI. When the mobile device establishes a radio resource and a connection with the wireless access node, the globally unique identifier CGI identifying the wireless node is obtained from the broadcast channel, and the CGI is recorded when the wireless resource release is in an idle state; Step S1004, the UE sends the wireless When the resource establishment request (RRC Connection Request) carries the CGI, for example, when a large number of devices move to a new wireless node (the maximum number of allowed access users N_m _ax _all _0we d, the number of accessed users N_access), when the service is initiated within the coverage, CGI is filled in the information recording RRC Connection Setup Request message; step S1006, the wireless node determines whether the current access is required within a predetermined time T exceeds the number of users allowed to access _{N_} uSer the number of users within a predetermined time N_t_user_max, i.e., determining T Whether N_user is greater than N_t_user_max in the time, the judgment result is yes If yes, go to step S1008, otherwise go to step S1014; Step S1008, determine whether the sum of the required user data N_user and the number of existing access users N_access exceeds the maximum number of allowed access users N_max_allowed, that is, judge N_user and N_access And if N_m _ax _all _0we d is exceeded, if the judgment result is yes (that is, the current wireless access node is in an overload state), go to step S1010, otherwise go to step S1212; step S1010, the current wireless access node adjusts the maximum allowable The number of access users is N_max_allowed+N_user, and the radio resources are allocated to the user equipment that is required to be accessed, and the new required access with the same CGI is extracted according to the CGI information carried in the RRC Connection Setup Request. The number of users N_same_cgi_i ( i = l , 2 , ... η ) , N_same_cgi_i <= N_user , N_same_cgi_l + ... + N_same_cgi_n = N_user; Step S1012, according to the CGI notification to the original eNodeB for load adjustment (Load Number Adjust); current wireless The number of allowed access users (N_max_allowed+) increased by the access node is equal to the number of allowed access users (M_max_allowed-) reduced by the original wireless access node, and N_max_allowed+=M_max_allowed-=N_user, that is, the current wireless access node passes the X2 interface. The original wireless access node (Load Number Adjust) corresponding to the CGI information is respectively notified, and the maximum number of allowed access users max_allowed-N_same_cgi_i of the original wireless access node is adjusted to ensure the maximum number of allowed access users per wireless access node. The sum does not exceed the maximum value of the core network accommodating user; in step S1014, the current wireless access node (ie, the new eNodeB) provides a service for establishing a connection for the new access user equipment. When the current wireless access node releases the mobile device, the mobile device records the CGI information of the current wireless access node and replaces the CGI that has been provided to the current wireless access node. Through the above steps, the wireless access node can dynamically adjust the maximum allowable access load of the node according to the mobility of the UE, and all nodes adaptively adjust to achieve load balancing effect. It should be noted that when the user equipment migrates to other When the new wireless access node is used, the CGI information is provided to the new wireless access node, and when the new wireless access node is overloaded, the maximum number of allowed access users of the original wireless access node and the new wireless access node is re-adjusted. Through the foregoing embodiment, the mobile device is used to record the original wireless access node identification information, and after moving to the new wireless access node coverage, the original node CGI information is provided to the new node when the service is performed, and if the new node is in an overload state, The maximum number of access loads can be accurately adjusted, and the original node reduces the maximum number of access loads because the mobile device is not in the coverage of the original node, so that the total number of wireless node loads does not exceed the maximum number of users in the core network. The load balancing method does not interrupt the user services that have been accessed and does not affect the service access of new users. The number of node access users in the entire network changes continuously with the migration of mobile devices, and does not cause overload of the wireless nodes after load balancing. Signaling between network elements occurs only with the migration of mobile devices. Network signaling does not appear redundant, and has the advantages of load balancing purpose and accuracy. 11 is a flowchart of a mobile device load balancing processing method under EUTRAN according to a preferred embodiment of the present invention. As shown in FIG. 11, the process includes the following steps: Step S1102: A mobile device UE sends a radio resource establishment request to an eNodeB_1, that is, The mobile device UE starts to camp on the cell covered by the eNodeB_l, and completes the location registration or attach process with the MME through the eNodeB_1; the UE performs voice or data services, and the eNodeB 1 allocates radio resources to the UE, establishes a wireless connection, and completes In the data bearer setup process, the MME provides services for the UE, the UE reads the CGI information from the eNodeB_1 broadcast channel, and the UE stores the CGI when the service ends the radio resource release; Step S1104: The mobile device UE sends a radio resource setup request to the eNodeB_2, that is, the UE moves. The coverage to the eNodeB_2, when the UE initiates the service procedure, when the RRC Connection Setup Request is initiated, the eNodeB_1 will carry the CGI information when communicating with the eNodeB_2; in step S1106, the eNodeB_2 adjusts the access load, when a large number of UEs are migrated from other eNodeB_l coverages. When the eNodeB_2 coverage is performed, the eNodeB_2 is required to allocate radio resources for communication. The eNodeB_2 checks whether the number of UEs that initiate the service within the specified time T exceeds the maximum number of allowed access users of the eNodeB_2 configuration time, and if not, proceeds to step S1114. If it exceeds, it is checked whether the number of accessing UEs and the total number of users that have been accessed currently exceed the specified maximum number of allowed access users. If the maximum number of allowed access users N_max_allowed is not exceeded, then go to step S1114. If the maximum number of allowed access users N_m _ax _all _0we d is _exceeded , the number of UEs having the same CGI information, N_same_cgi_i (i=l, 2, ...n), is extracted according to the CGI information provided by the UE, and N_same_cgi_l+ is guaranteed. .. +N_same_cgi_n= N_user _; for example, eNodeB_2 adjusts the maximum allowed access number N_max_allowed+N_user; Step S1108, eNodeB_2 load number adjustment is sent to eNodeB_1, ie eNodeB_2 notifies N_same_cgi information to eNodeB_1 _; Step S1110, eNodeBJ receives load number adjustment message After the notification, adjust the access load number, that is, according to the N_same_cgi value, reduce the maximum number of allowed access users to N_max_allowed - N_same_cgi. The eNodeB_1 and the eNodeB_2 adaptively adjust the corresponding N_max_allowed value according to the UE mobility situation; in step S1112, the eNodeB_2 performs radio resource establishment and data bearer processing with the UE that requires access, releases the radio resource after the service ends, and records the eNodeB_2. the CGI information; for example, the following approach: eNodeB_2 requires access to radio resources are allocated to the UE and establishes a connection, the UE provides access services; step S1116, CGI information _{e NodeB_2} UE reads the broadcast channel, in the business The CGI information of the eNodeB_2 is recorded when the release of the radio resource returns to the idle state. If the UE restarts the service within the coverage of the eNodeB_2, it will carry the CGI information of the eNodeB_2. At this time, the eNodeB_2 does not change the current maximum number of allowed access users, nor does it notify other wireless access nodes to perform adjustment; when the UE moves to the new eNodeB When the coverage results in a new eNodeB load process, the new eNodeB re-implements load balancing according to the content of step S1108 according to the CGI information provided by the UE.
